Description

Technical Field

[0001] This application belongs to the field of building support technology, and specifically relates to a convenient perforated floor support frame fixing device. Background Technology

[0002] In recent years, with the rapid development of large, high-rise, and super high-rise buildings, the application of perforated floor structures in high-rise buildings has become increasingly widespread. However, these types of floors generally suffer from the problem of easily damaged perforated edges, leading to misalignment of the support frame during upper-level construction and inaccurate positioning during movement. Therefore, effectively fixing the support frame of perforated floors has become a key control point in the construction of such projects.

[0003] Traditional support frame systems typically involve laying steel plates and rubber mats to cover the construction area after the concrete of the perforated floor has reached the required strength, and then placing the support frame on the steel plates. While this method is simple to construct, it has significant drawbacks: First, it consumes a large amount of materials, requiring significant manpower and resources for each relocation, resulting in serious resource waste and poor economic efficiency; second, the support frame system is heavy, placing additional pressure on the perforated floor and increasing safety hazards; third, insufficient positioning accuracy makes it prone to misalignment and displacement, affecting construction quality and efficiency.

[0004] Therefore, there is an urgent need for a new type of fixing device that can solve the problems of excessive materials, heavy weight, and easy misalignment in traditional support frame systems. Utility Model Content

[0005] The purpose of this application is to provide a convenient perforated floor support frame fixing device. This addresses the problems of traditional support frame systems, such as the large amount of material required, heavy weight, and susceptibility to misalignment, as mentioned in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A convenient perforated floor support frame fixing device is provided, including at least two first connecting rods, a reinforcing component and a second connecting rod;

[0008] The first connecting rods are respectively installed on the periphery of the support frame column;

[0009] One end of the first connecting rod is connected to one end of the reinforcing member, and the other end of the reinforcing member is connected to the second connecting rod. The second connecting rod is located near the inside of the floor opening, and at least two second connecting rods are used to fix the floor opening.

[0010] In one possible implementation, the reinforcing member is a turnbuckle.

[0011] In one possible implementation, the second connecting rod includes a horizontal portion and a vertical portion;

[0012] One end of the horizontal part is connected to the turnbuckle, and the other end is vertically connected to the vertical part, which is used to extend into the floor opening.

[0013] In one possible implementation, the length of the vertical section is greater than the depth of the floor opening.

[0014] In one possible implementation, a reinforcing block is provided on the side wall of the vertical section near the floor opening.

[0015] In one possible implementation, the reinforcing block is provided with a rubber pad near the floor opening.

[0016] In one possible implementation, the rubber pad is configured as an elastic buffer pad that is fitted to the surface of the floor opening.

[0017] In one possible implementation, the rubber pad is detachably fixed to the reinforcing block.

[0018] In one possible implementation, the first connecting rod, the turnbuckle, and the second connecting rod are all made of high-strength steel.

[0019] In one possible implementation, the first connecting rod is detachably connected to the support frame column.

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] This application provides a convenient perforated floor support frame fixing device, which forms a multi-directional fixing structure around the support frame column by combining at least two first connecting rods, a reinforcing component and a second connecting rod. Compared with the traditional single-point fixing method, it can significantly improve the overturning resistance and horizontal positioning accuracy of the support frame on the perforated floor, avoid misalignment or displacement caused by insufficient force at a single point, and at the same time, disperse the load through multi-directional coordinated force distribution to reduce local damage to the floor edge.

[0022] In one possible implementation, the adjustability of turnbuckles allows for quick fastening and disassembly of the support frame: during positioning, tightening the nuts shortens the distance between the connecting rods, firmly inserting the second connecting rod into the floor opening; after construction is completed, loosening the turnbuckles allows for quick movement of the device without disassembling the overall structure, significantly improving construction efficiency while avoiding the tedious process of repeated disassembly and assembly required by traditional bolt fixing, thus reducing labor costs.

[0023] In one possible implementation, the reinforcing block increases the contact area between the vertical part and the sidewall of the hole, dispersing the concentrated load into a surface load and preventing the concrete at the edge of the hole from cracking due to excessive local stress.

[0024] In one possible implementation, the reinforcing block increases the contact area between the vertical part and the sidewall of the hole, dispersing the concentrated load into a surface load and preventing the concrete at the edge of the hole from cracking due to excessive local stress.

[0025] In one possible implementation, high-strength steel ensures that the fixing device does not deform or break when subjected to vertical and horizontal loads from the support frame, thus improving structural safety; hot-dip galvanizing enhances corrosion resistance, making it suitable for high-rise construction in humid or high-salt-spray environments, extending the service life of the device, and reducing safety hazards caused by material corrosion.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this application discloses a convenient perforated floor support frame fixing device, which may include at least two first connecting rods 1, a reinforcing member 2, and a second connecting rod 3.

[0037] Optionally, the support column is a circular steel structure column, with four first connecting rods 1 evenly arranged along its circumference. One end of each first connecting rod 1 is fixed to the support column by bolts, and the other end is connected to one end of the reinforcing member 2. The other end of the reinforcing member 2 is connected to a second connecting rod 3. One end of the second connecting rod 3 extends into the rectangular hole of the perforated floor, and the other end is horizontally connected to the reinforcing member 2. The four second connecting rods 3 clamp the edge of the hole from different directions, forming a stable quadrilateral fixing structure.

[0038] In this embodiment of the application, a multi-directional fixing structure is formed around the support frame column by combining at least two first connecting rods 1, a reinforcing member 2 and a second connecting rod 3. Compared with the traditional single-point fixing method, it can significantly improve the overturning resistance and horizontal positioning accuracy of the support frame on the perforated floor, avoid misalignment or displacement caused by insufficient force at a single point, and reduce local damage to the floor edge by dispersing the load through multi-directional coordinated force distribution.

[0039] In one possible embodiment, the reinforcing member 2 is configured as a turnbuckle.

[0040] The reinforcing component 2 uses a commercially available standard turnbuckle, which includes a double-ended screw and an adjusting nut. The first connecting rod 1 and the second connecting rod 3 are respectively screwed into the two ends of the turnbuckle. By rotating the adjusting nut, the screw spacing can be shortened or lengthened, thereby tightening or loosening the connection between the second connecting rod 3 and the support column.

[0041] In this embodiment, the adjustability of the turnbuckle allows for quick fastening and disassembly of the support frame: during positioning, the distance between the connecting rods is shortened by tightening the nut, and the second connecting rod 3 is firmly inserted into the floor hole; after construction is completed, the device can be quickly moved by loosening the turnbuckle without disassembling the overall structure, which significantly improves construction efficiency and avoids the cumbersome process of repeated disassembly and assembly required by traditional bolt fixing, thus reducing labor costs.

[0042] In one possible embodiment, the second connecting rod 3 includes a horizontal portion 31 and a vertical portion 32.

[0043] One end of the horizontal part 31 is connected to the turnbuckle, and the other end is vertically connected to the vertical part 32, which is used to extend into the floor opening.

[0044] The second connecting rod 3 is an L-shaped metal rod. The horizontal part 31 is 30cm long. One end has a threaded hole for connection with the turnbuckle bolt. The other end has a vertical part 32 with a length of 25cm welded on it. The total length is such that the vertical part 32 extends 5cm beyond the depth of the hole after being inserted into it. The end of the vertical part 32 is smoothed to avoid scratching the edge of the hole.

[0045] In this embodiment, the L-shaped structure makes the second connecting rod 3 form a "hook" effect. The horizontal part 31 is connected to the support frame column by turnbuckle. After the vertical part 32 extends into the hole, the horizontal part 31 and the vertical surface of the hole edge form a stable fulcrum, which can effectively resist the horizontal displacement and vertical pull force of the support frame. Compared with the straight rod structure, it is less likely to fall off. At the same time, the L-shaped design reduces the amount of material used and reduces the weight of the device.

[0046] In one possible embodiment, the length of the vertical portion 32 is greater than the depth of the floor opening.

[0047] The hole in the perforated floor is 20cm deep, and the vertical part 32 of the second connecting rod 3 is designed to be 28cm long, ensuring that it extends 8cm beyond the inner wall after being inserted into the hole. The end of the vertical part 32 contacts the inner wall of the hole, forming a two-way fixing structure of "outer clamping and inner top".

[0048] In this embodiment, the length of the vertical part 32 is greater than the depth of the hole, so that the second connecting rod 3 forms a "cantilever support" in the hole. The end of the rod abuts against the inner wall of the hole, which can simultaneously withstand horizontal thrust and vertical tension. This avoids the problem of only hooking but not tightening due to the vertical part 32 being too short, and significantly improves the pull-out resistance and overall stability. It is especially suitable for high-rise construction scenarios with large loads.

[0049] In one possible embodiment, the vertical section 32 is provided with a reinforcing block 33 on the side wall near the floor opening.

[0050] A rectangular reinforcing block 33, measuring 5cm × 5cm × 1cm, is welded to the vertical part 32 near the side wall of the hole. The reinforcing block 33 is made of steel plate and is flush with the vertical surface of the vertical part 32, increasing the contact area with the side wall of the hole.

[0051] In this embodiment of the application, the reinforcing block 33 increases the contact area between the vertical part 32 and the side wall of the hole, thereby dispersing the concentrated load into a surface load and avoiding cracking of the concrete at the edge of the hole due to excessive local stress.

[0052] In one possible embodiment, the reinforcing block 33 is provided with a rubber pad 34 near the floor opening.

[0053] A 5cm×5cm×0.5cm rubber pad 34 is attached to the surface of the reinforcing block 33 near the inside of the hole with epoxy resin adhesive. The surface of the rubber pad 34 has a grid pattern to enhance the friction with the wall of the hole.

[0054] In this embodiment, the rubber pad 34 serves as an elastic buffer layer, which can absorb the vibration load of the support frame during construction, reduce the rigid impact on the edge of the perforated floor, and avoid edge damage caused by direct contact between traditional metals. At the same time, the friction of the rubber pad 34 can help fix the second connecting rod 3, prevent it from sliding in the hole, and further improve the positioning accuracy.

[0055] In one possible embodiment, the rubber pad 34 is configured as an elastic buffer pad that is fitted to the surface of the floor opening.

[0056] Specifically, the rubber pad 34 is made of nitrile rubber with a thickness of 8mm. Its shape matches the curvature of the inner wall surface of the hole; for example, a rectangular hole corresponds to a rectangular rubber pad 34, and a circular hole corresponds to an arc-shaped rubber pad 34. It is molded to ensure a perfect fit to the wall surface.

[0057] In this embodiment, the fitting design of the elastic buffer pad can eliminate the gap between the metal component and the concrete wall, forming a seamless contact. This not only enhances the sealing performance but also avoids stress concentration by uniformly distributing the load. At the same time, the deformation capability of the elastic material can adapt to slight deviations in the size of different holes, improving the versatility of the device.

[0058] In one possible embodiment, the rubber pad 34 is detachably fixed to the reinforcing block 33.

[0059] Optionally, the reinforcing block 33 has a groove on its surface, and the rubber pad 34 has a protruding buckle on its back that matches the groove. The buckle is inserted into the groove to achieve a detachable connection, and the rubber pad 34 can be quickly replaced after it wears out.

[0060] In this embodiment, the detachable design facilitates the maintenance and replacement of the rubber pad 34: when the rubber pad 34 ages or breaks due to long-term use, it is not necessary to disassemble the entire fixing device. The old pad can be removed and the new pad can be inserted to complete the replacement, reducing maintenance costs and extending the overall service life of the device, which is in line with the recyclable concept of green construction.

[0061] In one possible embodiment, the first connecting rod 1, the turnbuckle, and the second connecting rod 3 are all made of high-strength steel.

[0062] Optionally, the first connecting rod 1, the turnbuckle, and the second connecting rod 3 can all be made of Q355B high-strength steel, hot-dip galvanized, with a surface roughness Ra≤12.5μm and a tensile strength≥470MPa, to meet the construction load requirements of high-rise buildings.

[0063] In this embodiment, high-strength steel ensures that the fixing device does not deform or break when subjected to vertical and horizontal loads of the support frame, thus improving structural safety; hot-dip galvanizing enhances corrosion resistance, making it suitable for high-rise construction in humid or high-salt-spray environments, extending the service life of the device, and reducing safety hazards caused by material corrosion.

[0064] In one possible embodiment, the first connecting rod 1 is detachably connected to the support frame column.

[0065] Optionally, the first connecting rod 1 is connected to the support frame column by a U-bolt: bolt holes are opened on the surface of the support frame column, and through holes are provided at the end of the first connecting rod 1. After the U-bolt passes through the hole, it is locked with a nut. When disassembling, simply loosen the nut to separate the first connecting rod 1 from the column.

[0066] In this embodiment, the detachable connection allows for quick adaptation to different types of support frames. By replacing the first connecting rod 1 or adjusting the connection position, the device can be reused in various construction scenarios. At the same time, the disassembled device components can be transported and stored separately, saving storage space, reducing transportation costs, and improving the flexibility and convenience of the construction site.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
